Engineered for extreme environments, this device is certified to endure 25 falls from 4 feet and can survive accidental drops of up to 25 feet onto concrete. It operates reliably in temperatures ranging from -40°F to +140°F, ensuring performance in the harshest climates. Inside, the integrated XCell sensors detect gas hazards twice as fast as the industry average, allowing for 50% faster bump tests and calibrations while consuming half the test gas. Furthermore, the MSA GALAXY® GX2 system allows for automated, scheduled maintenance at your preferred time of day.
